I brought my car to Preferred Supreme Auto Repair for an Inspection. The sales person name was Steve. I left the auto with them about 12pm Monday, April 12, 2010. When I returned at 2pm they brought my car out to me and I happen to check for my navigation system that I left in car by mistake.. Well the navigation system was gone. I used it the night before so I know it was in the car when I left it with them. I spoke to steve about it and I was told there was no navigation system in the car when I brought it in. Now I do not know how he would have know if it was in there or not but it  was gone. I called the police and filed, a report. Even the officer who spoke to Steve and the other worked said that hem "knowS" what happen to it but it is hard to prove. So Warning to all you people who bring your car to Preferred Supreme Auto repair on 4585 Amboy road in Staten Island. Beware, do not bring your car there for anything. Or at least take Everything out of it before you leave it with them.
